Abstract
Dental materials are specific materials that were developed as a general
materials for specific aplication in oral environment. To determinate the
functional properties of this materials, we are obligated to use nonstandard
approach and specific methods. In this study, two methodologies of material
testing-artificial agging and quantification of visual informations for life
circle assessment of hydroxyapatite (Hap) based materials, were used. Hap was
chemically synthetized which produced the material with high purity and
crystallinity. Artificially produced Hap is used in stomatology for repair of
bone tissue, as a filling for periodontal defects, and as a preservative
augmentation for alveolar ridges. In the mean time those materials are used
for definitive root canal obturation in endodontic therapy procedure as an
apical plug or as complete filling material. This research was focused on the
analysis of the bonding properties of the Hap based materials to the root
canal walls. The methodology of artificial agging was used together with the
quantification of visual informations in purpose to quantify the Hap bonding
properties and bonding quality. Experiments were done in-vitro, with the
artificia saliva as the agressive agent. The experimental tooths were
analyzed by the high resolution optical microscope for the morphological
characterisation of the bonding layer. The model for the bond life circle
assessment was developed. Hap based materials proved that has favorable
properties for the dental use. The presented results proved that the
combination of two methodologies (artificial agging and quantification of
visual informations could be used as the tool for analyzing the
material-dentine interaction.
